A young girl with multiple diastemas and peg lateral in the upper anterior region was treated with composite recontouring and reshaping of the concerned teeth. Composites propose a minimally invasive means of esthetic rehabilitation in such cases as opposed to prosthetics and the time consuming orthodontic treatment modalities. Additionally, composites are durable, less time consuming, inexpensive and easily repairable.

2 Endodontics, Government Dental College, The patient chose to go ahead with the last option Ahmedabad with the chief complaint of gaps in the upper front teeth region. Detailed history from the patient revealed the patient had previously undergone orthodontic therapy for four years. However, non compliance on the patient s part resulted in the orthodontic treatment getting stranded midway. The patient was seeking a matrimonial alliance and had faced multiple rejections due to her unesthetic smile. The patient had finally found a suitable match for herself and now wanted esthetic correction of the anterior teeth before her wedding day which was 2 months away. Clinical examination revealed diastemas in the upper anterior region among the teeth from upper as it was least time consuming and the least expensive amongst all the available options. TREATMENT Upper lower diagnostic casts were studied and wax mock up performed (Fig 2). A putty template was made using addition silicone (AFFINIS putty soft, Coltenewhaledent). On the scheduled appointment, patient was comfortably seated and the mock up cast was shown to her. Prophylactic scaling followed by polishing was done using rubber cup and pumice slurry. Once the patient was satisfied with the expected result as seen on the mock up cast, shade selection was done using Ivoclar Vivadent shade guide in natural daylight. Lip and cheek retractor right canine to upper left canine (Fig 1). Upper (Optragate, IvoclarVivadent) was applied to right lateral incisor was peg shaped (Fig 1). The upper right and left premolars and lower left lateral incisor were missing. The patient had a cross bite (Fig 1) on the right side of the upper lower arches. The dental midline was shifted 3 mm (Fig 1) to the left side. Radiographic examination was done using OPG. Upper and lower diagnostic impressions were made and casts were poured. OPG confirmed the clinical findings of missing teeth. The diagnostic cast was used to study the patient s occlusion and dental anatomy. Treatment planning was done on the study cast. All treatment options were explained to the patient. improve access and visibility. A bevel preparation was done in the enamel of the teeth that were to receive the restoration i.e. upper canine to canine. Teflon tape was applied on the right and left premolars. Total etch technique was used. 37% phosphoric acid (N -Etch, Ivoclar Vivadent) was used to etch the teeth for 15 seconds. Bonding agent (Tetric N Bond Universal, Ivoclar Vivadent) was applied using an applicator tip and cured using a curing light (Bluephase N, Ivoclar Vivadent) for 20 seconds. The putty template was placed and palatal wall was Orthodontic correction in collaboration with built using flowable composite (Tetric N-Flow, restorative correction of malformed teeth and prosthetic rehabilitation of the missing teeth was one option. Another alternative was to go for fixed dental prostheses (indirect restorations) correcting the shape, size and contour of the maxillary anterior teeth. The other alternative given to the patient was the use of composite resin to camouflage the diastemas and recontour the maxillary anterior teeth to improve the esthetics. Ivoclar Vivadent). The composite (Tetric N-Ceram, Ivoclar Vivadent) was placed and condensed in increments using the OptraSculpt instrument (Ivoclar Vivadent) (Fig 3). Each increment was light cured using a curing light (Bluephase N, Ivoclar Vivadent) for 10 seconds. Flossable contacts were created using cellophane strips. The occlusion was checked and adjusted. The restorations were then finished using finishing burs 6

However, the use of direct composites for diastema closure must be limited to patients with excellent oral hygiene. In order to discourage the retention of plaque, and its seen in Fig 5 and 6. associated loss of gingival health, it is essential to It has been one year since the restorations were performed.

Meticulous maintenance of oral hygiene in addition to well-polished restorations can prevent adverse periodontal affects of even overcountoured Orthodontic correction in collaboration with and intrasulcular direct composite restorations. 4 restorative treatment would have resulted in correction of the midline shift and cross bite followed by esthetic rehabilitation of the peg lateral and closure of any remaining diastemas using The main disadvantage of composite resin is the possible need for multiple replacements during the lifetime of the patient. The passage of time is not as kind to composite as it is to porcelain and composite recontouring.

However, that would involve unnecessary loss of sound tooth structure. develops. 5 Therefore patients should be made aware that the shade and texture of the composite material will probably change with time, and that it may require periodic replacement. 6 Arguably, the surface Direct composite resin restorations are a texture of composite veneers is not as natural in conservative therapy that can provide a good treatment outcome in diastema closure. Both esthetics and function are enhanced and, in most cases, little or no preparation of the tooth is appearance as porcelain. In addition, most practitioners find it harder to create teeth directly in the mouth compared with a technician workin required. 1 good esthetic outcome, durability, g at a laboratory bench. If anatomic nuances are not affordability are some of the advantages of the contemporary composite materials. Additionally, their longevity of adhesion to enamel is well documented. Physical and chemical improvements over the years have optimized color stability and improved wear resistance. 2 Also, composites are kinder to the opposing dentition as compared to ceramics used in case of veneers and crowns. The added advantages of direct bonding include ease intraoral repairability, the opportunity to sculpt the restoration, low costs, and possibility of completing the restoration in a single visit without the need to incur laboratory fees. 3 Further, direct bonding is advantageous in that it allows modification while the patient is still undergoing followed, an unesthetic V-shaped diastema closure may result. 3 A 5 year follow up study by Frese et al on diastema closure and recontouring of teeth using direct composite build up revealed an overall survival rate of 84.6% after 5 years and clinically acceptable quality parameters at follow up. The authors also stated that the functional survival rate of 100% is attributable to the ease of reparability of such restorations. 7 The diagnostic mock up technique used in this case gives the patients a fair idea of the anticipated results simply by looking at the diagnostic casts making it easier for the clinician and the patient. 8 The use of the specialized instrument 7

Tetric N-Ceram composite material wasused for its nano-optimized filler content which is is responsible for the material s unique chameleon effect and natural esthetic results. It demonstrates an exceptionally high level of radiopacity and thus significantly facilitates the diagnosis of secondary caries. The Nano-fillers results in low shrinkage and shrinkage stress, low wear, fast polishability and high gloss. The nano-modifier ensures optimum stability, excellent sculptability and convenient handling properties. The biggest advantage is that polymerization in only 10 seconds ( mw/cm2 per increment) is possible. The patient s needs should be the prime concern governing treatment planning. In this case the time constraint and the esthetic correction were the two main concerns of the patient. The decision to go ahead with esthetic rehabilitation without correction of midline shift and crossbite was keeping in mind the patient s needs and its urgency. The best possible treatment plan in the minimum available time was thus, adopted. CONCLUSION: There has been a significant shift from need based treatment modalities to esthetically defined treatment modalities in dentistry. The patient today is more concerned and aware of his appearance and does not wish to compromise on that. Thus, it is upon the dentist to strike a balance between function and esthetics to deliver the best to his patient. Composites provide for a minimally invasive, durable, inexpensive and easily repairable treatment modality in such cases. Additionally, it is less time consuming and allows for any number of manipulations to the restorations to suit the patient s desires. With all its advantages, composite camouflaging as a treatment modality is here to stay and must be explored by the dentist alone or in collaboration with other specialities such as orthodontic and prosthetic corrections, in order to deliver best results to their patients.
